  2. Ceiling (aeronautics) - Wikipedia

    en.wikipedia.org/wiki/Ceiling_(aeronautics)

    The service ceiling is the maximum altitude of an aircraft during normal operations. Specifically, it is the density altitude at which flying in a clean configuration , at the best rate of climb airspeed for that altitude and with all engines operating and producing maximum continuous power, will produce a given rate of climb.

  3. Coffin corner (aerodynamics) - Wikipedia

    en.wikipedia.org/wiki/Coffin_corner_(aerodynamics)

    Coffin corner (also known as the aerodynamic ceiling [1] or Q corner) is the region of flight where a fast but subsonic fixed-wing aircraft's stall speed is near the critical Mach number, at a given gross weight and G-force loading. In this region of flight, it is very difficult to keep an airplane in stable flight.

  4. Flight envelope - Wikipedia

    en.wikipedia.org/wiki/Flight_envelope

    This maximum altitude is known as the service ceiling (top limit line in the diagram), and is often quoted for aircraft performance. The area where the altitude for a given speed can no longer be increased at level flight is known as zero rate of climb and is caused by the lift of the aircraft getting smaller at higher altitudes, until it no ...

  5. Rate of climb - Wikipedia

    en.wikipedia.org/wiki/Rate_of_climb

    V x increases with altitude and V Y decreases with altitude until they converge at the airplane's absolute ceiling, the altitude above which the airplane cannot climb in steady flight. The Cessna 172 is a four-seat aircraft. At maximum weight it has a V Y of 75 kn (139 km/h) indicated airspeed [4] providing a rate of climb of 721 ft/min (3.66 m/s).

  6. Angle of climb - Wikipedia

    en.wikipedia.org/wiki/Angle_of_Climb

    This is important for clearing an obstacle, and therefore is the speed a pilot uses when executing a "short field" takeoff. V X increases with altitude, and V Y decreases with altitude until they converge at the airplane's absolute ceiling. Best angle of climb (BAOC) airspeed for an airplane is the speed at which the maximum excess thrust is ...

  7. Aircraft Industries L 410 NG - Wikipedia

    en.wikipedia.org/wiki/Aircraft_Industries_L_410_NG

    Aircraft Industries L 410 NG ("New Generation") is a twin-engine 19-seat aircraft manufactured by the Czech company, Aircraft Industries (formerly Let Kunovice). The aircraft is an upgraded version of the Let L 410 UVP-E20.

  8. Aérospatiale SA 315B Lama - Wikipedia

    en.wikipedia.org/wiki/Aérospatiale_SA_315B_Lama

    SA 315B Lama, 2003. The Lama was developed specifically to provide a rotorcraft with exceptional high-altitude performance. In practice, the type found considerable use within regions that possessed extensive mountain ranges, such as South America and India, being capable of lifting loads and deploying personnel in areas that had been previously impossible to have otherwise achieved.

  9. Instrument flight rules - Wikipedia

    en.wikipedia.org/wiki/Instrument_flight_rules

    A safety pilot's primary duty is to observe and avoid other traffic. [ 16 ] In the UK, an IR (UK restricted) - formerly the "IMC rating" - which permits flight under IFR in airspace classes B to G in instrument meteorological conditions, a non-instrument-rated pilot can also elect to fly under IFR in visual meteorological conditions outside ...
